BUTTON.

SPECIFICATION forming part of Letters Patent No. 377,446, dated Pebruary'7, 1888.

Application filed September 14. 188

To aZZ whom it may concern:

Be it known that we, GUMBY S. BLUM, Jr., and JosEPH A. PHILLIPS, citizens of the United States, residing at Baltimore, in the. State of Maryland, have inventedcertain new and useful Improvements in Buttons; and We do hereby declare the following 'to be a full, clear, and exact description of the invention,

This invention relates to certain improvements in buttons, and it has reference more particularly to buttons of that class in which two metallic disks, one provided with a cross-' bar and the other with a hub and central opening, comprise the essential parts of the button. In buttons of this description previously constructed the thread holding the button to the garment was considerably chafed and cut by coming in contact with the sharp interior edge of that portion of the rear disk forming the central opening, which has usually been turned'direotly toward the bar and almost surrounds the thread. Furthermore, these buttons have been somewhato bjectionable, for the reason that the cross-bar as hitherto formed has not been of such strength as to withstand any considerable amountof strain.

The object of our invention is to overcome these and other objectionable features; and to this end it eomprisesa button in which the inner edge of the opening or hub of the rear disk is turned outwardly'from the center and to ward or upon itself, in which the cross-barof the front plate'is considerably strengthened by the peculiar conformation given it, and in which other features are embodied, that will be hereinafter referred to, and pointed out in the claims. it

In the accompanying drawings, wherein slmilar letters-of reference indicate like parts, Figure 1 is an enlarged top or plan vi'ew of our improved button;- Fig. 2, a cross-section of the same 011 line at a; of Fig. l, and Fig. 3 a crosssection on line 3 3 of Fig. 1.

Referring to the drawings, A represents the front disk or plate, having the cross-bar a, over which the thread is passed, formed integral therewith. This disk may be ol -ornamental brass or other suitable metal, and is preferably curved, as shown in Fig. 2, to give added flexi 7. Serial No.a49,674. (NomodelJQ its central portion,forming, in connection 55 with the front disk, a sinuous convex curve. By this construction thestrain upon the crossbar a, is directly in linewith the texture of the metal, and is not exerted in an angular direction. At its junctions with the disk A the bar a is preferably made slightly wider, forming the rounded corners e. .metal from splitting, and gives the crossbar added strength at the point where it is ordinarily weakest. By reason of this depressed portion of the'bar the thread is further kept in linewith the center of the button, and is This prevents the g consequentlypreve'nted from'being chafed by d theedges of the front disk.

B, Figs. 2 and 3, shows the. rear disk, held in place by the overlapping edges of thefront disk, A,in the usual manner. The edge of the hub b of this disk is turned inwardly and upon itself in orderto form the circular flange b, having its edges turned back toward the wall of hub 12, so as to present a flaring and pr-' fectly smooth and rounded eyelet-shaped opening- The edge of the flange 12 before being subjected to the turning-in operation is slightly countersunk, as shown at c, in order to thin out the metal at this point and'insureits uniform expansion. may turn up and finish this portion of the h against an interior die or former. a

Fig. 3 is a crosssectional view of the button on line y y of Fig. 1, showing the ears formed in punching the front diskturned under the cross-bar to. strengthen it at'its central depressed portion, and showing,also, the rounded and gradually-widening shape of -the cross-bar at its junction with the front disk,A. It will thus be seen that our button will not only withstaud a very considerable strain upon the cross -bar, but offers a rigid and extremely smooth hub .that is devoid of any sharp edges and cannot abrade or otherwise injure the retaining-thread or the garment to'which it is I attached. 7 Furthermore, by virtue of the shape given to the front disk and bar, agreater de-f g gree of flexibility and strength is imparted to. it, and the button is more readily inserted in and removed from the button-hole.

In some cases, however, we

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. As an improved article of manufacture, a button of the class described, having the central portion of its back plate or disk perforated and turned upward and outward within the interior of the button, so as to form a smooth eyelet-shaped passage for the retaining-thread, substantially as set forth.

2. A button comprising,substantially,afront disk or shell, having a bar or other thread-support formed integral therewith, and a rear disk or shell provided with a hub and central opening, the metal forming the lower edge of said [5 hub being countersunk and turned upward and outward within the interior of the button, substantially as and for the purpose set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
